If you have sufficient signal strength but unusable signal the problem
*might* be reflections, but it could be interfering signal(s), either
on-frequency or even off-frequency if the signal is of sufficient
strength to create mixer garbage in the HDHR.
Sometimes *reducing* the input level to the tuner (with an attenuator)
will actually make things better. You'd need a signal level meter or the
like to really know what's going on.
Does the signal look OK going directly into a TV set? (assuming you have
one capable of ATSC)? Do you have any neighbors getting good or bad ATSC
reception?
